Abstract. There is a great need to differentiate drainage oil and normal oil. To establish rapid and effective methods to judge the oils, the objective of this research was to study the feasibility of using transmitted light and reflection light to differentiate drainage oil and normal oil. Transmitted light was obtained by an UV-Vis spectrophotometer. Petroleum ether as solvent, oil samples were scanned with 200nm to 1000nm transmitted light with scanning speed at 1m/s. The scanning results indicated that oil and petroleum ether at volume ratio of 1:50 was suitable to obtain a clear scan profiles. Obvious absorbance profiles appeared at wavelength between 200 nm and 400 nm. The given wavelength scanned results indicated that there was an obvious difference at 280 nm for all of the oil samples. CIELAB and RGB color of the drainage oil and the normal oil were analyzed. Results indicated it was hard to adopt hues to differentiate the drainage oil from the normal oil.
